T all whom it may concern:

I Be it known that I, REGINALD HAZELTINE, V

a citizen of the United States of America,

residing at Chicopee Falls, in the county of Hampden and State of Massach-usetts, have invented certain new and useful Improvements in Gages, of which the following is a specification. L4 7 v This'invention" relates generallyto gages and more particularly to improvements in mgage mountings .or holders, by means of which the gage may be used with greater convenience and with improvedaccuracy on certain classes of work. 7 V V 1 While the invention is capableof general application, it finds one advantageous'use as a means for measuring the thickness of fabit to the measuring device is, in itself, time 'ric during steps in its manufacture. For

example, fabric used in the manufacture of tire shoes is frictioncoated with rubber-in a calendering machine. During the calendering operation, itis desirable to frequently 7 test the thickness of the fabric -and it has been the custom to cut from theweb of fabric small samples which are subsequently smoothed out flatand'measured with an ordinary gage. Thecutting ofsamples, necessarily means that a certain percentage of 1 -the' fabric is wasted and, moreover, the operation' of cutting the sample and'carr'ying consuming. The described general-practice I of" measuring work of the character dej scribed has been rendered necessary in, that accurate measurements "could notreadily j'be made with existing types of-measuring apnee'ds' be held flat during the'gaging operation, and the springs ofthe usual gage are *the gage against the fabric with the necesinsufficient to move the measuring foot of sary' force for this purpose.

Other objects and advantages vill appear s5 poses-inthe accompanying drawings, in whlchz r form of the invention, the indications of the gage are intended to be visible throi'igh a glass g.

The gage G is suitably fastened to the upstanding arm of an angle bracket 5, and its plunger f/ depends freely through an opening 6 provided in the other arm of bracket In spaced parallel relation with and below the long arm of bracket 5 is an anvil 7 with which the foot of plunger 9 is adapted to engage. The bracket 5 and anvil 7 are adjustably secured together. As shown in Fig. 2, the bracket 5 and anvil 7 have integral and inwardly turned extensions 8 and 9, respectively, and between the latter is a rocker 10, which rests in suitable recesses in the extensions and permits limited rocking movement of the one relatively to the other. Two screws 11, one 'on each side of the rocker 10, pass loosely through the extension 9 and are threaded into extension 8. .By loosening one screw 11 and tightening the other, the bracket 5 may be rocked relatively to, and moved toward or away from, the anvil 7. Thus, the anvil 7 and bracket 5 may be rigidly held in the desired spaced relation but in such a manner as to permit adjustment of the distance be tween them, as desired.

On the opposite side of the extension 9 from the anvil 7, a handle portion 12 is provided, which may be readily and conveniently grasped for the purpose of carrying and supporting the entire assembly described. It is to be noted that, asonegrasps the handle 12 in the natural manner, he

necessarily faces the glass g of the gage,

and thus is in a position to conveniently read the indications thereof.

The remaining and the most important feature of the invention consists in the provision of a presser foot which functions to flatten out the" articles to be measured against the anvil 7 and also functions as a means for separating the foot f of the gage plunger 9 from the anvil 7. This presser foot consists of a flat member 13 having an opening 1% to loosely encompass the foot f. A coiled spring 15, disposed between the bracket 5 and the 'presser foot, n'ormally urges the latter with considerable force against the anvil 7 or against an article thereon, which is to be ga'gcd, as a sheet S of fabric, for example. The-foot-13-has two spaced upstanding and upwardly inclined webs-16, which straddle the extensions 8 and 9 and are pivoted to the latter at 17. The webs 16 are bridged at their upper portions by a part18, which forms a thumb piece, the latter being so arranged as to be convenient-ly engaged by the thumb of the same hand which is employed tograsp the handle 1-2. Consequently, the presser foot 13 may be readily and conveniently separated from the anvil by depressing the thumb piece 18.

anvil 7 on the otherside of the sheet.

Upon the prcsser foot 13, is secured a forkshaped piece 19, which has its free and forked end so disposed as to partially encompass the plunger foot f. Adjustably secured to the plunger g and overlying the forked end of piece 19 is a collar 0, and the latter is adjusted so that, when the foot 7 is in engagement with anvil 7 it will lie slightly above and out of engagement with the forked piece 19. When, however, the thumb piece 18 is depressed to separate the presser foot 13 from the anvil 7, the forked piece 19 will engage collar 0 and raise the gage plunger 9, thereby separating the foot f from the anvil. The clearance between collar 0 and the forked piece 19 has been punposely exaggerated in Fig. 1 for the purpose of clearness in the illustration. In practice, this clearance may be made very small so that the foot y is separated from anvil 7 by a distance very nearly equal to and substantially the same as that by which...

the uses to which it may be put. Assuming that the sheet S, represented in cross-section in Fig. 2, is moving through a machine, such as a calendering machine, for example, the operator merely stops the machine for a moment to permit the gaging operation. Then with the handle portion 12 grasped by the four fingers and palm of one hand and the thumb piece 18 depressed by the thumb of the same hand, the holder is slipped edgewise over the sheet S so that the presser foot 13 and gage foot lie on one side and the The thumb piece 18 is next released, which allows the presser foot to be forced, by the relatively strong spring 15, into engagement with sheet S, whereby the latter is flattened out and firmly held for the gaging operation. The lowering of the piece 19 with the presser foot, permits the gage plunger 9 to be lowered independently by reason of 1 the usual gage spring (not shown) until its foot 7 engages the sheet S. The operator may then convenient-1y read the indication of the gage through the glass g, which he faces, and thereafter, by depressing thumb piece 18 to elevate the jpresser foot 13 and gage foot-f, withdraws the gage holder from the machine.

It will thus be seen that a gage holderhas been provided which is particularly suited and thumb .piece is considered important in that ready, convenient, and eflicient operation'of the gage is permitted in theperformance ofwork of the character described. The

provision of a combined work pressing foot and gage plunger lifting device is also important and advantageous. The arrangement of a presser foot of relatively large area, which is operable entirely independent of the gage plunger and yet is operable to lift the latter when such lifting is required, constitutes an essential feature of the present invention. According to the last-named arrangement, improved accuracy in measurement may be obtained in that the foot f may be made of very small area, since it has no function in holding the Work to the anvil, and in that the presser foot may be made'as large as is necessary or desired, since it opcrates independently of the gage .plunger to firmly hold the Work to the anvil during the gaging operation.

The invention has been disclosed, in an embodiment at present preferred, for the purposes of illustration, but the scope of the invention is defined by the appended claims rather than by the foregoing description.

What I claim is- 1. In a device of the class described, a support, a gage thereon, an vanvil connected with said support, a plunger for the gageto cooperate With the anvil, a presser foot yieldingly forced against the latter to hold an article to be measured against the anvil independently of said plunger, said presser foot being manually retractable from said anvil, and means operable on retraction of said presser foot to separate said plunger from the anvil.

2. In a device of the class described, a support, a gage thereon, an anvil connected to the support, a plunger for the gage mounted to reciprocate to and from said anvil and normally held against the latter, a pivoted lever having a relatively large presser foot portion to loosely encompass said plunger, means yieldingly forcing the presser foot against the anvil to grip an article to be measured independently of the gage plunger, said lever being manually operable to lift the presser foot away from the anvil, and

means operable by the lifting of the presser foot to lift the gage plungerifrom the anvil.

3. In a device of the class described, a holder including a handl portion, a gage support and an anvil, a gage carried by said support and so arranged With respect to the handle portion that its indications are readily visible tothe one by Whom the handle portion is grasped, a gage plunger to cooperate with the anvil, a lever pivoted intermediate its ends to the holder, said lever having atone end a relatively large presser foot to cooperate with the anvil and at the other end an actuating portion so located With re- Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
